A transaction card comprising, such as a credit card or debit card, includes transaction card serial number information that identifies the transaction card, sender authentication information identifiable by location information and location information is on the transaction card. In addition, account information is also on the transaction card.

Transaction card for providing electronic message authentication

A method, apparatus and/or system generates a challenge for user authentication, having a challenge data element from a stored pool of challenge data elements. The challenge is based on rule data and stored usage data associated with at least some of the challenge data elements in the stored pool of challenge data elements. The generated challenge is sent for use in an authentication of a user to a sender. A method, apparatus and/or system also generates sender authentication and corresponding location information, having a data element from a stored pool of challenge data elements. Selection of the data elements is based on rule data and stored usage data associated with at least some of the data elements in the stored pool of data elements.

Method and apparatus for providing authentication between a sending unit and a recipient based on challenge usage data

Methods and apparatus for judicially storing information to enable fast information retrieval are disclosed. The information is organized in information fields each field having a respective set of information elements. Cells of information elements are defined and corresponding information records are cached. The cells may be user defined or formed based on affinity coefficients of pairs of information elements. With a large number of fields, each having a large number of information elements, cells are generated recursively. Each cell is associated with at least one pre-defined query.

Methods and system for information storage enabling fast information retrieval

A method for providing electronic message authentication employs an article, such as a card, sticker, or any other suitable article, that includes sender authentication information and location information such as row and column headings. In one example, each recipient of interest is issued an article that embodies unique sender authentication information that is identifiable by corresponding location information such as column and row identifiers. In both an apparatus and method, when the sender of an electronic message wants to send a message to a recipient of interest, the sender sends the electronic message and both location information and corresponding desired sender authentication information located at the coordinate identified by the location coordinate information. If the sent desired sender authentication information matches authentication information found on the article, the sender of the message is trusted.
